I am trying to send a double/float over SPI from my SAMD21 based board, with chip select on pin A1/A2. I have copied some code from the internet, but I don't really understand it, plus it only works for sending data between two Arduino Unos. Here is my master:
#include <SPI.h>
float a = 3.14159;
float b = 2.252332;
uint8_t storage [12];
float buff[2] = {a, b};
void setup()
{
digitalWrite(SS, HIGH);
SPI.begin();
Serial.begin(9600);
SPI.setClockDivider(SPI_CLOCK_DIV8);
}
void loop()
{
digitalWrite(SS, LOW);
memcpy(storage, &buff, 8);
SPI.transfer(storage, sizeof storage ); //SPI library allows a user to
//transfer a whole array of bytes and you need to include the size of the
//array.
digitalWrite(SS, HIGH);
delay(1000);
}
And here is my slave:
#include <SPI.h>
byte storage [8];
volatile byte pos;
volatile boolean process;
float buff[2];
void setup()
{
pinMode(MISO,OUTPUT);
SPCR |= _BV(SPE);
SPCR |= _BV(SPIE);
pos = 0;
process = false;
Serial.begin(9600);
}
ISR(SPI_STC_vect)
{
byte gathered = SPDR;
if( pos < sizeof storage)
{
storage[pos++] = gathered;
}
else
process = true;
}
void loop()
{
if( process )
{
memcpy(buff,&storage,8);
Serial.print("This is val1:");Serial.println(buff[0], 5);
Serial.print("This is val2:");Serial.println(buff[1], 6);
storage[pos] = 0;
pos = 0;
process = false;
}
}
Any help would be aprreciated, and please understand that I am a newb in this subject.
I have to do a project for Uni using 2 arduino uno, 2 HC 05 bluetooth module and 2 sensors for each arduino. I have set a module to be the slave, and the master connects to the slave only.
When I am trying to send the data from slave to be read by master, it keeps reading 0.
I am using Arduino IDE, I have no errors and everything runs.
This is the code I have so far.
Also, I want to send data from 2 sensors from the slave to the master, but I do not know how to do that.
Slave code
#include <SoftwareSerial.h>
#define TILT 7 // tilt sensor pin
#define LDR 8 //light intensity sensor pin
#define rxPin 10
#define txPin 11
SoftwareSerial nodeCommunication = SoftwareSerial(rxPin, txPin);
int sentBytes; ////// SLAVE CODE
byte data[2];
void setup() {
Serial.begin(9600);
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
pinMode(TILT, INPUT);
pinMode(LDR, INPUT);
Serial.begin(9600);
nodeCommunication.begin(9600);
delay(2000);
}
void loop() {
//int LDRval = analogRead(LDR); // light intensity sensor (candela)
//int Tilt_Sensed = digitalRead(TILT);
data[0] = analogRead(LDR);
data[1] = digitalRead(TILT);
if(nodeCommunication.available()){
sentBytes = nodeCommunication.write(data[0]);
Serial.println("I reached this if");
}
Serial.println(analogRead(LDR));
Serial.println(sentBytes);
delay(2000);
}
Master Code
#include "dht.h"
#include <SoftwareSerial.h>
#define dht_apin A0 // Analog Pin sensor is connected to A0
dht DHT; // DHT.humidity // DHT.
#define rxPin 10
#define txPin 11
SoftwareSerial nodeCommunication = SoftwareSerial(rxPin, txPin);
byte data = 1;
///// MASTER CODE
void setup(){
Serial.begin(9600);
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
nodeCommunication.begin(9600);
delay(2000);//Wait before accessing Sensor
}//end "setup()"
void loop(){
//Start of Program
DHT.read11(dht_apin); // reading the data from the sensor
if(nodeCommunication.available()){
data = nodeCommunication.read();
Serial.println("I reached this if");
}
Serial.print(data); Serial.println(" candela;");
Serial.print(DHT.temperature); Serial.println(" C");
Serial.print(DHT.humidity); Serial.println(" % humidity");
delay(2000);//Wait 2 seconds before accessing sensor again.
//Fastest should be once every two seconds.
}// end loop()
Please tell me what I am doing wrong. Thank you so much!
byte data = 1; - should be just byte data;
Have you checked the TX/RX connections? The TX from the master has to connect to the RX of the slave and visa versa. Als GND has to be connected to eachother.
After that, let the master (the transmitter) just Serial.write (in your case nodeCommunication.write() ) to the slave (the receiver).
So something like this:
Master:
#include <SoftwareSerial.h>
#define rxPin 10
#define txPin 11
byte data = 0x01; //Hex value for ''1''
SoftwareSerial nodeCommunication = SoftwareSerial(rxPin, txPin);
void setup()
{
Serial.begin(9600);
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
nodeCommunication.begin(9600);
}
void loop()
{
nodeCommunication.write(data); //Sends byte data to slave
delay(1000);
}
Slave:
#include <SoftwareSerial.h>
#define rxPin 10
#define txPin 11
byte incoming
SoftwareSerial nodeCommunication = SoftwareSerial(rxPin, txPin);
void setup()
{
Serial.begin(9600);
pinMode(rxPin, INPUT);
pinMode(txPin, OUTPUT);
nodeCommunication.begin(9600);
}
void loop()
{
if(nodeCommunication.available > 0) //Only if data is available
{
byte incoming = nodeCommunication.read(); //read byte from master
Serial.println("Incoming = ");
Serial.println(incoming);
}
else
{
Serial.println("No data available....");
}
}
After your Serial communication is established, implementing the DHT value will be the next step.
I am trying to verify the Arduino code in ADS1198 and Arduino Due. It comes the error show 'Serial1' does not name a type' even I defined two serial port in the beginning(where I gave the comments now).

I want to use bluetooth connection to control, how long something is on. So I read the Serial Input. If it is a number, I take the number and put it into a delay. After it is through, I write something and check again. If the Serial Read is not a number, it should turn off. in The problem is, the led keeps running. Do you see, what is my mistake?
#include <SoftwareSerial.h>
#define ledPin 13
#define rxPin 10
#define txPin 11
SoftwareSerial btSerial(rxPin, txPin);
int btData;
void setup() {
btSerial.begin(9600);
btSerial.println("bluetooth available");
pinMode(ledPin,OUTPUT);
serv.attach(3);
serv2.attach(5);
}
void loop() {
if (btSerial.available()){
btData = btSerial.read();
if(isDigit(btData)){
digitalWrite(ledPin,1);
btSerial.println("LED on Pin is on");
delay(btData*10);
}
else {
digitalWrite(ledPin,0);
btSerial.println("LED on Pin is off");
}
}
delay(100);
}
Try to use this:
#include <SoftwareSerial.h>
#define ledPin 13
#define rxPin 10
#define txPin 11
SoftwareSerial btSerial(rxPin, txPin);
int btData;
void setup() {
btSerial.begin(9600);
btSerial.println("bluetooth available");
pinMode(ledPin,OUTPUT);
serv.attach(3);
serv2.attach(5);
}
void loop() {
if (btSerial.available())
btData = btSerial.read();
if(isDigit(btData)){
digitalWrite(ledPin,1);
btSerial.println("LED on Pin is on");
delay(btData*10);
}
else {
digitalWrite(ledPin,0);
btSerial.println("LED on Pin is off");
}
delay(100);
}
And the reason is because the enabling and disabling was done only when there is serial data and if you put the if anywhere else it would be checked always.
I must send 3 values gave by 3 potentiometers ,connected by an Arduino Uno, and send them to another Arduino Uno whith a serial comunication. The received values must be distributed in 3 servo motors so that each knob able to control the servo motor movement.
the problem with this program is that the values received are not distributed correctly (for example the case that the value of the potentiometer 1 is to be read by the servo motor 3 or other cases). I ask if I could help to synchronize data received with the distribution of them to the servo motors. Thanks in advance.
